however, is that the table tends to wabble be cause it is supported in the center only.

One ob ect of this invention is to overcome 15 this defect by providing a table which is supported entirely or partly at its outer edge, particularly at the point where the cutting takes place. In this manner, the cutting pressure of the knife may be absorbed directao ly so that the work table is relieved of strains and may be operated with greater safety.

Fig. 1 is a longitudinal section of the inachiine substantially on line l1 of Fig. 2; an

Fig. 2 is a plan view of the machine. The slicing machine is supported on a base framel whlch carries a bracket 2 in which the shaft 3 of the knife 4 is journalled. The machine is driven by a hand crank 5 which 30 rotates the horizontal driving shaft 6. At the end of the driving shaft 6 1s a bevel gear 7 which meshes with a bevel gear 8 on the vertical drivin shaft 9. The drive of the knife 4'consists o a bevel'gear 10 mounted on the 35 short shaft 11 and meshing with the bevel gear 8, and a sprocket wheel carrying a chain 12 is mounted on the other end of the shaft 11.

The driveofthe rotatable work table con- 40 sists of a spur gear 14 rigidly connected with thebevel gear 8 and in mesh with a chain 15 arranged on a flange or skirt portion of the work table 13. The chain 15 is arran within, a channel bar 16 secured at the ower end of the inner wall of the work table 13. The lower flan e of the channel bar. 16 rests on the track 17 o the base frame 1 in order to support the table 13 against "the pressure ofthe knife. The track 17 may extend around the entire circumference of the 5 table or it may extend over,a portion of the circumference a'ajacent the knife, as shown table 13 on the track 17. The pin 18 may be locked by set screws 20 after the desired e5 adjustment is made.

The work table 13ipreferably is mounted by .means of ball bearings 21, 22 on the pin 18, said ball bearings being adapted to take up vertical and horizontal pressure. The To work table 13 is provided with four slides 23 of which two only are shown in the drawing. The slides are movable along the rods 24 about which they may be tilted. Each slide 23 engages a feed spindle 26, journaled below 75 the work table, through a segmental nut 25. The feed spindle is operated by a feeding device 27 whose feed lever is provided with a roller 28 which travels once during each rotation about the inclined plane 29. A hand wheel 30 is provided to render the feed spindle 26 manually adjustable. j The feed is controlled by a small hand crank level 31 which adjusts a. shaft32. At the end.v of the shaft 32, an'ecoentric 33 is secured, which may be so positioned that the feed pawl is in engagement .with the feed wheel a longer or shorter time, as may be desired. The-construction of this part of the U 35 r movement of the table away from the cutting feeding device is well known and need not further be described.

Each slide 23 of the work table 13 is provided with a meat clamping device 34:, which is of well-known construction, and is adjustable, as is also well-known in the art.

The manual drive of the machine obviously may be replaced by a motor drive which may be connected with the knife.

I claim i 1. In a slicing machine having a rotating slicing knife and a work table mounted to rotate so that the periphery of said table moves past the cutting edge of said knife, mechanism for continuously rotating said table, and means for supporting said table near its outer edge to prevent movement thereof away from the cutting portion of the knife edge.

2. In a slicing machine having a rotating slicing knife and a work table mounted to rotate so that the periphery of said table moves past the cutting edge of said knife, mechanism for continuously rotating said table, a support for supporting the outer edge of said table, and means adjustable to vary the pressure of said table on said sup port.

3. In a slicing machine having a rotating slicing knife and a work table mounted to rotate its periphery past the cutting edge of said knife, driving mechanism for rotating said table, co-operating driven means on the outer edge of said table, and a support positioned adjacent said driven means to resist portion of said knife and for supporting the outer edge of said table.

4. In a slicing machine having a slicing knife and a work table, an upright shaft upon which said table is journaled. gear teeth receiving means adjacent the periphery of said table, driving mechanism having a gear meshing with said means to rotate said table past the cutting edge of said knife, said gear teeth being arranged on the periphery of a flange extending around said table and concentric with said shaft.

5. Ina slicing machine having a slicing knife and a work table, an upright shaft upon which said table is journaled, gear teeth receiving means adjacent the periphery of said table, driving mechanism having a gear meshing with said means to rotate said'table past the cutting edge of said knife. and a track upon which the outer edge of said table rests for preventing movement of said table away from the cutting portion of said knife due to the force exerted by said knife during the cutting operation.

6. In a slicing machine having a slicing knife and a work table, an upright shaft upon which said table is journaled, gear teeth receiving means adjacent the periphery of said table, driving mechanism having a gear work-carrying portion and a skirt portion extending downwardly from the peripher of said work-carrying portion, an upright shaft upon which saidtable is journaled, gear teeth receiving means on said skirt portion, driving mechanism having a gear meshing with said means to rotate said table past the cutting edge of said knife, and a track disposed under said skirt portion to support said table.

8. In a slicing machine having a rotating slicing knife, a work table comprising a work-carrying portion and a skirt portion extending downwardly from the periphery of said work-carrying portion, an upright shaft upon which said table is j ournaled, gear teeth receiving means on said skirt portion, driving mechanism having a gear meshin with said means to rotate said table past t e cutting edge of said knife, and work feeding mechanism carried by said table below said work carrying surface and within said. downwardly extending skirt portion.

9. In a slicing machine having a rotating slicing knife, a work table comprising a workcarrymg portion and a skirt portion extending downwardly from the periphery of said work-carrying portion, an upright shaft upon which said table is j ournaled, gear teeth receiving means on said skirt portion, driving mechanism having a gear meshing with said means to rotate said table past the cutting edge of said knife, and means adjustable to raise and lower said shaft to vary the pressure of said table on said track.

10. In a slicing machine having a rotating slicing knife, a work table comprising a workcarrying portion and a skirt portion extending downwardly from the periphery of said work-carrying portion, an upright shaft upon which said table is ournaled, a channel bar carried b said skirt portion, a chain in said channel ar, driving mechanism having a gear engaging said chain to rotate said table past the edge of said knife, and a track upon which said channel bar is supported.

11. In a slicing machine having a rotating slicing knife, a work table comprising a workcarrying portion and a downwardly extending skirt portion, work feeding mechanism nected when said table is rotated past a predetermined position.

13. A slicmg machine comprising a slicing knife, a table, a lurality of carriages slidably mounted on sai table, means for moving said table past said slicing knife to bring each of said carriages successively past said slicing knife, and automatically feeding means for feeding said carriages as said carriages pass a predetermined position, said feeding means I 7 being disposed beneath said table and substantially concealed thereby.

In testimony whereof I have signed my name to this specification on this 27th day of January A. D. 1928.
